Question Pc gets stuck on bios on startup

[JamesSkyfire1611]

Hello all,

Upon turning my pc on this morning, the lights clicked on, then off, then the rig starts up, fans start spinning etc.

It then gets stuck on the AMIBIOS screen (american megatrends), the one where it shows you what motherboard and processor you have, memory, detected drives, etc. (it does display a cpu fan error on the attached picture, but that has been displayed on that screen since i first built the pc, never caused any issues, so i do not think it is related at all. ) However I have never noticed the paragraph below the cpu fan error, detailing intel optane memory or raid config, so maybe that could be something.

So anyways on this amibios screen, I have to press F1 to run setup, which takes me into the bios, from there i can access the boot menu and choose the windows boot manager to load from.

I then get a republic of gaming logo appear on screen with a buffer icon.

it then displays another screen, with just the buffer icon

after a while, windows loads up and i can use everything as if nothing was wrong at all.

I have tried doing a system restore, but the issue still persists. I have tried turning the pc on with nothing else plugged in besides the display port and power adapter. As well as unplugging all external drives and my other ssd.

I ran into a similar issue to this a while back, where my pc would not turn on at all, lights and fans would keep flicking on and off.aThis happened after not using the computer for a few monthes, due to being away from home for a bit. After numerous reboots, unplugging everything etc, it did finally turn on, whereby my pc installed an nvidia update and windows update, and then it has worked fine ever since. However there has been the occasional time where the pc just turns itself off and reboots. Just thought i should mention this event, just in case it could shed light on what is going on now.

I havent installed any new hardware to the build, the spec sheet included is the same it has been since i put it all together.

I will post pictures of my pc specs and the screens i have mentioned above.

I installed a new cmos battery, which doesnt seem to have done much. It didnt do the click on and off, before turning on when i got home from work today. So I'm wondering if that has been fixed, however I did leave the machine plugged in, so I will find out in the morning after turning it off at the wall, whether that issue has potentially been fixed. I still get stuck on this american trends screen, i always have to manually go to the boot menu and boot windows that way. I'm wondering if it's just a fault with the motherboard, or perhaps my bios is damaged somehow. Faulty ssd perhaps? I'm going to dust off the manual tomorrow and see if there is a way to restore the bios to factory settings. Otherwise I have no idea what to do.

You probably have the CPU fan plugged into the CPU OPT rather than just the CPU header, they typically are right next to each other. I recommend fixing that first. Once you have done that, update your bios to latest (v. 2401) and report back.

Since the battery was already replaced, the remaining things that seem most likely are failing boot (or other but you unplugged those to test) drive, bad cable or partially disconnected/fouled contacts at either end, or failing PSU, possibly on the 5VSB rail if it runs okay once it boots... except you stated it doesn't quite, that it reboots on its own.

I assume you are not overclocking. If you are, undo that for further testing. Did you try loading and saving the bios defaults after replacing the battery? Did you look around in the SATA mode/raid setup menu to see if something looked wrong since the bios stops at that displayed message?

It's not going to be something happening within windows, stops before it loads the OS. However you wrote that it stops and reboots, so if you have the windows setting to reboot on error turned on, turn that off and see if you get a bluescreen or other error message. If you don't, I'm leaning towards it being the PSU flaking out.

In rare cases, a failing power-on case switch can cause odd behavior but wouldn't usually make the bios halt on same message like that unless it just happens to take the same exact # of seconds to get to that point, then would normally shut off or restart the bios sequence again, but it is pretty easy to just unplug the mobo power (and reset if so equipped) switch and short the power on pins together to rule that out.

FYI it is better to host images somewhere else like imgur and embed them in your post rather than having everyone click through to another site to see them, especially for people using a phone, tablet, or less than large monitor.
